The Four Avenues are a group of four major arterial boulevards — Bealey Avenue, Fitzgerald Avenue, Moorhouse Avenue, and either Rolleston Ave or Deans Avenue — that surround the city centre of Christchurch, New Zealand. Serving as an inner ring road, they popularly form the limits of the city centre, separating it from the city's suburbs. Almost all of the city's commercial heart lies within the approximately rectangular 9.8-square-kilometre (3.8 sq mi) area formed by the four avenues. The term "within the Four Avenues" is widely used in Christchurch to refer to the central city. By extension, Christchurch as a whole is sometimes referred to as "The Four Avenues".

A boulevard is a type of broad avenue planted with rows of trees, or in parts of North America, any urban highway or wide road in a commercial district.
